Key point # 1
Even the most disparate organisms share some features, suggesting that a single, nonrandom
process generated diversity. - ANSWER ✔✔
Why is life so incredibly diverse yet so strangely similar? - ANSWER ✔✔ Evolution
How many species are there on planet earth? - ANSWER ✔✔ Probably between 3-5 million.
True or False? Biodiversity on Earth will likely decrease in the near future - ANSWER ✔✔ True
What is the definition of natural evolution? - ANSWER ✔✔ evolution by natural processes
What is the definition of creation? - ANSWER ✔✔ species created by a god
What is the definition of theistic evolution? - ANSWER ✔✔ evolution guided by a god
True or False? Scientists believe in evolution even though they currently lack evidence for the
theory. - ANSWER ✔✔ False
Key point #2 - Biologists accept evolutionary theory because its predictions match observations.
- ANSWER ✔✔
Use this information to answer the questions below.
In ancient Greece, some scholars viewed irrational numbers as heretical. These numbers could
never be described perfectly because they ran on for an infinite number of decimal places. The
opponents of irrational numbers argued that a perfect universe, designed by the gods, had no
place for imperfect numbers. Ultimately, irrational numbers played a major role in the
development of mathematics, as evidenced by their widespread use today. For example, the most
famous irrational number, Pi, enables one to calculate many properties of geometric shapes. -
ANSWER ✔✔
Opposition to irrational numbers was based on evidence that such numbers cannot exist.
a. True
b. False
,c. I don't know the answer - ANSWER ✔✔ False - (No direct evidence for or against irrational
numbers was used to oppose the idea. A religious belief based on faith was used instead.)
Opposition to irrational numbers stemmed from a worldview involving naturalistic evolution.
a. True
b. False
c. I don't know the answer - ANSWER ✔✔ False - (A creationist worldview was the reason for
opposing irrational numbers.)
3. The belief that irrational numbers cannot exist reflects religion more than science.
a. True
b. False
c. I don't know the answer - ANSWER ✔✔ True - (The notion that God(s) created a perfect
world is the product of a religion)
4. Modern mathematicians accept irrational numbers because such numbers provide more
accurate solutions to problems than whole numbers do.
a. True
b. False
c. I don't know the answer - ANSWER ✔✔ True - (irrational numbers are used because they
enhance calculations of measurable properties, such as the area of a circle).
Can you describe what we mean by science? - ANSWER ✔✔ Science literally means
"knowledge", being derived from the Latin word scientia. As with other scientific disciplines,
such as physics or chemistry, biology is the pursuit of knowledge about our world. More
specifically, biology is the pursuit of knowledge about life
What are some of the key features of science? - ANSWER ✔✔ Scientists use the following
methods:
careful observation
record keeping
mathematical reasoning
experimental tests
review by peers
communication to the public
1. The scientific method relies on ____________.
, a. models
b. observations
c. experiments
d. all of the above
e. I don't know the answer - ANSWER ✔✔ c. experiments
2. A model is a formal description of a scientific hypothesis. Which of the following types of
models provides the most precise description of a hypothesis?
a. verbal
b. graphical
c. mathematical
d. All of the above are equally precise
e. I don't know the answer - ANSWER ✔✔ c. mathematical
3. An experiment enables one to demonstrate that a correlation between two variables results
from cause and effect.
a. True
b. False
c. I don't know the answer - ANSWER ✔✔ a. True
4. A well designed experiment ___________.
Yes, that's correct!
a. controls for environmental and genetic factors.
b. involves the replication of experimental subjects.
c. randomizes experimental subjects among treatments.
d. achieves all of the above.
e. I don't know the answer. - ANSWER ✔✔ d. achieves all of the above.
